LCD replacement..

So the LCD wasn't working right on a compaq NX6110 that I have, so I decided to replace it as well as upgrade it to a SXGA+.. Now that I have replaced it it doesn't seem to work.. just changes different shades of grey and black.. ect. The laptop will run on an external monitor.. Its not the inverter, screen, or cable.. any ideas?

 

You know this because?

 

They're all new.

 

New does not necessarily mean that it's not the culprit, as parts have been known to arrive DOA (Dead on Arrival). There is also, as always, the possibility of damage upon installation, or possibly incompatibility issues if the new screen you've installed is not supported in either BIOS or if there are other hardware incompatibilities. Still, the first and simplest thing to check is that all parts are seated properly; makes sure all connections are secure, and that the cable isn't being crimped anywhere in the chassis.

 

How do you know the original issue was with the original LCD screen ? There might have been another issue causing the original LCD to malfunction and that might explain why this current one doesn't work. Also, as others have mentioned, just because the parts are new that doesn't mean they aren't defective

 

Yeah, them being defective may be possible. If it was indeed a bios problem, what do you think the best approach would be?

 

My brother had a nx6110 which I used to use as a test bed to test other screens . From my experience not all screens are supported. Here, I'm not talking about screen resolution but about screen ref. number and made. If the bios does not support a given screen then this screen won't work. You know it is like if you try to upgrade the intel wifi in your laptop with something that it is not made by intel. It simply won't work.

What I'm trying to say is that if you're sure that the LCD is not faulty (preferably by testing it in another laptop) then it is simply incompatible with your laptop .

 

If it is a BIOS problem, and you know for certain that the particular replacement screen you got is compatible with some version of the NX6110 (usually because there was a version sold with that specific brand and model of screen), then upgrading to the BIOS for that version of NX6110 should be enough to do the trick (usually just upgrading to the latest BIOS would do that, as BIOSes tend to be somewhat generic across a "family" of notebooks). Even then, success may not be entirely guaranteed; there was a post some time back about someone who replaced the LCD in their... Dell, I think it was, and during bootup, before the video drivers loaded, their screen would be distorted from a resolution issue.

 

You're right, Dell and (old) Toshiba are the worst when it come to screen replacement. I remember testing a 15.1" SXGA screen on my brother laptop, but I can't find its reference number
